HENRY L. GATES, OF MILWAUKEE, VVISOONSIN.

SHEET-METAL COAL-HOD.

SPECIFICATION forming part of Letters Patent No. 488,758, dated December27, 1892.

Application filed September 5, 1892. Serial No. 445,067- (No model.) 7

To all whom it may concern:

Be it known that I, HENRY L. GATES, a citizen of the United States, anda resident of Milwaukee, in the county of Milwaukee, and in the State ofWisconsin, have invented certain new and usefullmprovements inSheet-Metal Coal-Hods; and I do hereby declare that the 'following is afull, clear, and exact description thereof.

My invention has for its object to simplify and cheapen the productionof sheet-metal coal-hods; and it consists in certain peculiarities ofconstruction and combination of parts to be hereinafter described withreference to the accompanying drawings and subsequently claimed.

In the drawings: Figures 1 to 3 are diagrams illustrating the successivesteps in the method of joining the body and bottom of a coal-hodaccording to my improvements, said body and bottom being inverted. Fig.4, represents a side elevation of a completed coalhod embodying myimprovements, Fig. 5, a front elevation of the upper or funnel portionof the hod, Fig. 6, a diagram of the blank for the front section of thebod-body, Fig. 7, a detail horizontal section taken on line 77 of thesucceeding figure, Fig. 8, a detail vertical section on line 8-8 of Fig.4, illustrating one form of my improvements in the matter of joiningbail-ears to the body portion of the hod, and Fig. 9, a like viewillustrating another form of my improvements relative to joining thebail-ears and bod-body.-

Referring by letter to the drawings A represents the front and B therear section of a sheet-metal coal-hod body, these sections being joinedat their meeting edges by ordinary lock-seams b as is common in the art,and as it is also common in the art to make coal-hod bodies from asingle blank having its meeting edges seamed. I do not wish to beunderstood as limiting myself to any particular number of body sectionsor blanks in connection with the improvements hereinafter specified.

So far as I am' aware ithas heretofore been common in the art toprimarily flange the body and form an engaging head or fold in thebottom portion of a hod, then spring the body-flange into thebottom-bead and finally compress the seam thus formed to complete thejoint.

By my improvements I seek to do away with the preliminary fianging ofthe bod; and beading of the bottom, thereby saving the expense and laborof these two operations, as well as certain others incidental thereto,but not necessary to enumerate for the information of those skilled inthe art. In carrying out this portion of my invention I form the bottom0 of the hod in such a manner as to have an approximately verticalportion or wall 0 form an angle with an approximately horizontal portioncl, the diameter of said bottom at the angle thus formed being aboutthat of the bottom of the hod-body, which latterI make primarily withoutangle or bend at its lower edge and slip onto said bottom as clearlyillustrated in Fig. 1. Now by means of a suitable beading mechanism thebody and encircled bottom wall 0 are bent inward in such a manner as toform a common told one within the other as shown in Fig. 2, after whichthe fold thus formed is compressed, as shown in Fig. 3, by a drop-hammeror other suitable means, to complete the union of the hod-body andbottom. As will be seen by Fig. 2 it is preferable to have the loweredge of the hod-body double on itself when the beading operation takesplace, but this is not absolutely necessary to the carrying out of thepresent essential features of my invention, as it is possible to makesuch variation in the general contour of the bod-bottom and beadingmechanism that would result in but one thickness of said body beingcaught in the fold of said bottom, therefore it is to be un derstoodthat fundamentally my invention, as thus far described, consists in aresult due to the simultaneous flanging of a hod-body and the beading ofa hod-bottom engaged therewith. That portion 2 of the hodbottom beyondthe approximately horizontal portion d, in a direction opposite thewalls 0, is made flaring and curled or wired at the edge as is usual inthe art, while at the same time Iprefer to make the bottom properconcave, in order that when the compression of the fold, abovedescribed, takes place only the engaged thereby parts will offerresistance to the compressing mechanism, and in case a drop-hammermechanism is empldyed for the compressing operation, the bottom willaccurately center on a corresponding mandrel under the hammer, while inthe finished hod the concave bottom strengthens the whole.

When my improved coal-hods are provided with funnels, I. prefer to outthe front portion of the hod-body in such a manner as to leave enoughmetal to form said funnel in one piece therewith, it being preferableperhaps to cutthe metal as shown in Fig. 6, and join the projectingportions f thereof by an ordinary lock seam g, as best illustrated inFig. 5. However considerable variation may be made from the exactconstruction herein shown and specified.

In the manufacture of coal-hods it is usual to provide the ears, E, forbails F, with suitable openings for independent rivets passed throughthese openings and the bodies, but as shown by Figs. 7 to 9 inclusive Iprefer to form the bail-ears with integral projections h, that arestruck out from or cast with said ears accordingly as the latter are ofsheetsteel or malleable iron. In either form of bail-ears, theprojections h thereon may be driven through the metal forming thehodbodies, and this operation being completed, said projections areupset to retain the ears in place. 7

Having thus fully described my invention What I claim as new and desireto secure by Letters-Patent, is:

1. A method of making sheet-metal coalhods, that consists in forming thebottom thereof with a primary Vertically disposed wall at an angle to ahorizontally disposed portion, encircling said bottom wall with the bodyportion of the hod primarily devoid of angle or bend at its lower edge,simultaneously bending the parts thus engaged, and subsequentlycompressing the joint thus established, substantially as set forth.

2. A method of making sheet-metal coalh'ods, that consists in formingthe bottom thereof with a concave center and a primary verticallydisposed wall, the latter being at an angle to a horizontally disposedportion that is on a plane below the concavity, encircling said bottomwall with the body portion of the hod primarily devoid of angle or bendat its lower edge, simultaneously bending the parts thus engaged, andsubsequently compressing the joint thus established, substantially asset forth.

3. A method of makinga sheet-metal coalhod that consists in forming itsbottom with a primary vertically disposed wall at an an gle to ahorizontally disposed portion, encircling said bottom wall with the bodyportion of the bed primarily devoid of angle or bend at its lower edge,bending the bottom and body walls together to thereby fold the bodywallon itself within the bottom wall, and subsequently compressing theengaging folds, substantially as set forth.

.4. A two-part sheet-metal coal-hod having the lower edge of itsbody-wall folded on itself to form a two-layer flange engaging and thisflange engaged with a compressed bead in the bottom-wall of said hod,substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, atMilwaukee, in the county of Milwaukee and State of Niscousin, in thepresence of two witnesses.

It is hereby certified that in Letters Patent No. 488,758, grantedDecember 27, 1892,

upon the application of Henry L. Gates, of Milwaukee, Wisconsin, for animprovement in Sheet-Metal Goal-Bods, an error appears in the printedspecification requiring correction as follows: In line 69, page 2, theword engaging should be stricken out;

and that the Letters Patent should be read with this correction thereinthat the same may conform to the record of the case in the PatentOffice.
